I have a 75 gallon tank with 130W of PC light and no CO2. It is pretty well stocked with fish, so I do not dose NO3 very frequently, but try to keep it close to 20 ppm. Phosphate is kept between 1 and 2.5 (best I can tell with the test kit....) I have been dosing potassium 10 ppm when I do a weekly water change and 5 ppm every other day. Iron (CSM+B) is added once a week for about 0.01 ppm. Sword plants have been getting DIY root tabs once per week. Things have been going fairly well so far, but I have a couple of amazon sword plants that have small holes in a couple of the leaves and the remaining leaves are somewhat translucent. I know holes are associated with a potassium deficiency, but is it still reasonable to point the finger there given that I am now dosing about 25 ppm a week?
Just in the last couple of days, two crypts (bronze wendtii I am guessing--labeled simply as cryptocoryne at LFS) have started purging leaves as well. It is not melting in that the leaves are dissolving, they are simply coming off of the plant. They were not moved recently and had grown quite substantially from purchase several months ago.
Any guesses as to what should be done?
Thanks,
Chris
